Spheroidal ambisonics: Spatial audio in spheroidal bases [PDF]
JASA Express Letters, 2021 Ambisonics is an established framework to capture and reproduce spatial sound fields based on the spherical harmonics representation [Gerzon (1973). J. Audio Eng. Soc. 21(1), 2–10].

Assessing the ecological validity of soundscape reproduction in different laboratory settings [PDF]
PLoS ONE, 2022 The ever-growing body of soundscape research includes studies conducted both in everyday life environments and in laboratory settings. Yet, laboratory settings differ from in-situ and therefore may elicit different perceptions. The present study explores

Spatial Cues Provided by Sound Improve Postural Stabilization: Evidence of a Spatial Auditory Map? [PDF]
Frontiers in Neuroscience, 2017 It has long been suggested that sound plays a role in the postural control process. Few studies however have explored sound and posture interactions.

Multiple scattering ambisonics: Three-dimensional sound field estimation using interacting spheres [PDF]
JASA Express Letters, 2021 Rigid spherical microphone arrays (RSMAs) have been widely used in ambisonics [Gerzon (1973). J. Audio Eng. Soc. 21, 2–10] sound field recording. While it is desired to combine the information captured by a grid of densely arranged RSMAs for expanding ...

Directional Emphasis in Ambisonics [PDF]
IEEE Signal Processing Letters, 2018 We describe an ambisonics enhancement method that increases the signal strength in specified directions at low computational cost. The method can be used in a static setup to emphasize the signal arriving from a particular direction or set of directions.

Ambisonics Sound Source Localization With Varying Amount of Visual Information in Virtual Reality
Frontiers in Virtual Reality, 2021 To reproduce realistic audio-visual scenarios in the laboratory, Ambisonics is often used to reproduce a sound field over loudspeakers and virtual reality (VR) glasses are used to present visual information.

Assessing HRTF preprocessing methods for Ambisonics rendering through perceptual models
Acta Acustica, 2022 Binaural rendering of Ambisonics signals is a common way to reproduce spatial audio content. Processing Ambisonics signals at low spatial orders is desirable in order to reduce complexity, although it may degrade the perceived quality, in part due to the
